To all whom it may concern:

-Be it known that I,JOHN H. REsE, a citizen of'the United States, residing at Washington, in the District of Columbia, have invented a new and useful Improvement in Bottle Caps or Stoppers, of which the followinguis a specificatiom y invention relates to .closures or ca s for bottles and like vessels, being especial y adapted for use in making paper caps or stoppers for milk bottles; and it has for its object to produce a closure of novel and improved construction that may be made from stock sheet material and shall be.provided witha pulling. tab;

In the accompanying drawirigs-Fi ure -1 is a view of the upper ortion of a bottle, part of the neck thereof eing represented in section, and a closing cap made according to my invention being shown place thereina Fig. 2 a perspectlve view of a' cap. Fig. 3 is a lan view of a'sheet of material from whic the caps are made, re resenting the manner of cutting the caps om the stock material,

In the drawings, B represents a bottle such as is now commonly employed for the delivery of milk. Its neck is internally shoul dered at b to form an annular seat for the closing cap A which maybe, and usually is, formed of paper, it being intended that the caps shall each be used but once ,and then discarded. The body portion of the cap is in shape a circular disk from the edge of which,

extends a tab a of peculiar shape. The edge 2 of the disk is circular except for the break that occurs where the 'tab 0. joins the body. This tab under normal conditions, lies in the plane of the body A, though when put in place in a-bottle it is bent upward as indicated in Fig. 1. To facilitate this bending I prefer to score the disk on the up er surface, along a line that com letes the e ge circle 2, asindicated at 6. he tab. tapers towards its outer end 5, and has its opposite edges 4 and 5 curved, the line of each side or ed e being a reverse curve, as compared wit the peripheral curve of the body A, and flowing or springing therefrom, the radii of the severalcurves, 2, 4, and 5, being of equal length.

The lower or seating surface of the stopper is preferably curved or rounded alon the edge 2; but this edge, in thelane 0 the other surface is comparative y sharp. I have found that when thus formed the caps may be better seated in the bottle neck than when the edges are square cut.

There-are several advantages incident to a disk stopper or ca of the construction or form described. e tab is comparatively long permitting it to be easily gras ed when the cap is seated in the bottle nec ,and its outer exposed end is slender so that should it be engaged by some moving object it will yield without unseating the stopper. On the other hand the tab has'strength where strength is required, that is, alon the line of its juncture with the body A. urther, the peculiar shape is of advantage in the manuacture of the caps, as it permits of nearl all of a piece of stock material being utilized when the caps are cut out, as clearly indicated in Fig. 3, the material between adj acent bodies A constituting the tabs a. Another practical advantage is that the tools employed in cutting the disks are of simple shape and may be easily made without requiring the use of especially devised and expensive machinery.

While I have described a sealin disk made of paperand adapted to be use as a milk bottle stdpper, I wish it understood that my invention is not limited to any particular use or ada tation of the stopper or closure, nor to lits eing formed of any particular materia What-I claim is:

1. A sealin cap or closure 'comprisinga disk of suitabIe material, the body portion of which is of circular outline and from the ed e of which extends a tab, the opposite si es or edges of the latter being formed on reverse curves springing from the peripheral curve of the main body portion of the ca and uniting. at the outer'end of the tab, su stantially as set forth.

2. A sealin cap or closure comprising a disk of suitab e material, the body portion of which is'of circular outline and from the edge of which extends a tab a, the opposite edges of the latter bein formed on reverse curves springin from t e peripheral curve of the closure bein scored along the line of of which-is of circular outline and from the 10 juncture of the ho y A, and a tab; and the edge of which extends a pulling tab, the opposite edges of the tab being formed on seatin surface of the cap or closure being reverse cur'ves springing from the peripheral curveg or rounded along its edge, substancurve of the main body ortion A, and unittially as set forth.

ing at'the outer end of t e tab, substantially JOHN H. RESE.
